Benefits of technology

The patent describes techniques that allow a device to determine a filter coefficient based on the available measurements. This filter coefficient can be used to weigh the current received measurements based on previous filtered measurements. The device can choose the filter coefficient based on parameters like Doppler estimates, channel quality measurements, rotation estimates, and channel type information (line-of-sight or no line-of-sight). The technical effect of this patent is to improve the accuracy and reliability of measurement results in a wireless communication system, especially in cases where the signal quality is not optimal.

Problems solved by technology

However, it may be appreciated that in some such examples, channel conditions at the time of previous measurements may impact the outcome of the current measurement.

Abstract

Apparatus, methods, and computer-readable media for facilitating L1 UE-side filtering for mmW frequencies are disclosed herein. An example method for wireless communication at a user equipment includes configuring a filter coefficient for a serving beam. The example method also includes applying the filter coefficient to the serving beam to determine an updated filtered measurement result. The example method also includes reporting the updated filtered measurement result to a base station.

Description

CROSS REFERENCE TO RELATED APPLICATION(S)[0001]This application claims the benefit of U.S. Patent Provisional Application Ser. No. 62 / 866,541, entitled “Methods and Apparatus to Facilitate Layer 1 User Equipment (UE) Filtering for Millimeter Wave Frequencies,” and filed on Jun. 25, 2019, which is expressly incorporated by reference herein in its entirety.BACKGROUNDTechnical Field[0002]The present disclosure relates generally to communication systems, and more particularly, to beam management for wireless communications.INTRODUCTION[0003]Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources. Examples of such multiple-access technologies include code division multiple access (CDMA) systems, time division multiple a...
